A compact and autonomous corrosion sensor using the principle of electrical resistance variations of its metallic sensitive tracks has been used for different applications under atmospheric corrosion conditions. The measurements of the corrosion rate are performed in-situ both under laboratory and field exposures. From the results, it is possible to better understand the atmospheric corrosion of steel and zinc under various exposure conditions. The technique should also allow the design of reliable and realistic corrosion tests for different industrial applications.
